I know motorsports sells springs that drop the Z an inch an give an increase of 15-20% spring rate . If you measure the height of a 2+2 it is an inch lower, and if you look in the factory service manual you can see they are about 15% stiffer . Has anyone transpanted springs form a 2+2 over . It seems like a cheap alternative and would give a normal Z the extra edge .

Clint - word of caution

Clint,
Be sure you get a good set of springs. Yu'll be taking a chance with used ones that they'll be sagged. That happens over the years. New springs on my car raised it about 1. Old, sagged, springs ( I call them sprungs) will also shortenthe life on your struts - force them to work harder and wear them out prematurely.
My 2 cents worth,
Phantom

thanks for the compliment , Clint, but i've not been on this list before. i only found it about 2 days ago. i have owned this '78 coupe since it was new, however, so i have some experience and resources, having replaced almost everything on the car, some things more than once (like the springs) trying different things. Phantom makes a good point, being sure to start with in-spec parts.

I have a 75 280z 2+2 what would be a good source for new springs that are stiffer than stock no more than an inch lower than stock. Sam 75 280z

Clint, my '78 has a brand new single Turbonetics hybrid turbo, and it's not even broken in yet. it was a different Tim you corresponded with before. i know what you mean about out-of-control groups. the markiv (supra) guys play hardball but the hands-down winner (that would be losers) is turbobrick ( the volvo page ). talk about angry!!!

Sam, sorry i did't read your letter earlier (before i wrote to Clint), i could have combined the mail a little better to cut down on traffic but oh well, here goes... the hot setup now among my z friends is Eibach progressive springs and Tokico adjustable shocks. this is my next mod after the turbo gets dialed in.

Tim what do you get, what did you get Hmmmm!!
I myself am getting a new hybrid very soon . I plan to get the T3/T04E - 46mm trim, I picked this baby out a couple months ago after doing extensive research . It has very low end effeciency and it has a peak 76% eff . It should be very good up until about 17-18 psi more than I will ever need . I haven't talked to the guys at turbonetics yet, but this exact same turbo was in Sport Compact Car very good writeup . Let us all know how it works out .

Clint, i'm glad you mentioned scc mag because you are probably familiar with the work done by Alamo Autosport. i gave Steve there the specs and they did the rest. they put my whole system together (engine, turbo, dfi, ignition, exhaust) i believe what i have is 1 or 2 steps up from 18psi. it is really BIG. how's that for tech talk? it is limited to 5psi for break-in and the fact that i'm still saving for an intercooler) it sounds like you have really done a lot of research on your own. i'll find out the specifics on mine and let you know...
